the problem is that it's not really possible on arm
because you will need a toolchain for u-boot and an other for the userland
and in somecase an other for the kernel

We can not trust at all the libgcc provide by the toolchains we have see this
kind of problem thousand of times on the kernel and of course in U-Boot
and it's not the only arch to have this kind of problem the mips have too.

I can give 10's of toolchains which are correctly configured but never acheive
to build u-boot or the kernel just because of the libgcc.

Btw it will not be a huge work for U-Boot at all as we do this job in the
kernel anyway
